Dear all,
I would like to create a coordinate system in workbench by use of a Excel table.
(Xorig, Yorig, Zorig)+(CS Name) + (X axe Vector, Y X axe Vector, Z X axe Vector)

Origin+Name+Directional Vectors

I have identified the command/method in order to specify the coordinate system origine with

    **testCS.OriginX = Quantity(tempX,"mm")
    testCS.OriginY = Quantity(tempY,"mm")
    testCS.OriginZ = Quantity(tempZ,"mm") 
    testCS.name = "my coord"    **

But i wonder how can i specificy the Directional vectors for coordinate system orientation ?
Many methods are proposed by the editor but there are undocumented :-(
I have no idea of the appropriated syntax.

Can somebody has answer about this ?

Thank you,

best regards all,

    Not sure that we can define the Directional Vectors as they are read-only, even in the Mechanical interface (they are greyed out). However you can set the primary axis direction, as follows:

    coordinate_systems_1 = Model.CoordinateSystems
csys = coordinate_systems_1.AddCoordinateSystem()
# set primary X axis to arbitrary (1,2,3) direction
csys.PrimaryAxisDirection = Vector3D(1,2,3)
# place csys origin
csys.SetOriginLocation(Quantity(0,"in"), Quantity(0,"in"), Quantity(0,"in"))

    Thank you for your answer, it is clear.
    One direction is enough for me as i could align my CS to strain gauges alignment.
    Best regards
